固态继电器.安全要求

[中文适用范围]： 本文件适用于特定全有或全无电气继电器，称为固态继电器，旨在通过单步功能变化在OFF状态和ON状态之间以及反之改变电气电路的状态来执行电气操作。 本文件涉及旨在并入其他产品或设备中的固态继电器。因此，固态继电器被视为组件，本文件定义了作为独立组件的固态继电器与安全相关和功能的基本要求。 此类固态继电器被并入符合相关产品和/或应用标准的产品或设备中，以满足其预期应用。 注：以下是此类应用的示例： – 一般工业设备； – 电气设施； – 电气机器； – 电气器具； – 办公通信； – 建筑自动化和环境控制； – 自动化和过程控制； – 电气安装工程； – 医疗工程； – 电信； – 车辆工程； – 运输工程； – 照明控制。 作为设备的固态继电器： 当固态继电器被指定为对最终用户有功能的设备时，本文件给出了对EMC的要求。 作为组件的固态继电器： 对于设备制造商并入设备的固态继电器，没有EMC要求，因为性能在很大程度上取决于设备中的应用。 本文件的目的是说明： – 固态继电器的特性； – 适用于固态继电器的要求，参考： a) 电气安全； b) 其操作和行为； c) 其介电性能； d) EMC； – 验证要求是否满足的测试，以及采用的测试方法； – 固态继电器或产品文档中应提供的信息。 具有整体结构的固态开关器件属于IEC分委员会47E的范围，不在本文件中涵盖。 半导体控制器和接触器属于IEC 60947系列标准的范围—低压开关设备和控制设备—由IEC分委员会121A开发，不在本文件中涵盖。 [外文原描述]： IEC 62314:2022 applies to particular all-or-nothing electrical relays denominated solid-state relays intended for performing electrical operations by single step function changes to the state of electric circuits between the OFF-state and the ON-state and vice versa. This document deals with solid-state relays which are intended for incorporation in other products or equipment. As such, solid-state relays are considered to be components and this document defines the basic safety-related and functional requirements for solid-state relays as stand-alone components. Such solid-state relays are incorporated in products or equipment which themselves comply with the relevant product and/or application standard(s) to meet their intended application. Solid state relay as apparatus: Where the solid-state relay is specified as apparatus with a function to the end-user, requirements on EMC are given in this document. Solid state relay as component: There are no EMC requirements for solid-state relays intended for incorporation into the equipment by the equipment manufacturer, because the performance strongly depends on the application into the equipment. The object of this document is to state: – the characteristics of solid-state relays – the requirements which apply to solid-state relays with reference to a) electrical safety; b) their operation and behaviour; c) their dielectric properties; d) EMC; – the tests verifying that the requirements have been met, and the test methods to be adopted; – the information to be given with the solid-state relay or in the product documentation. Solid-state switching devices with monolithic structures fall within the scope of IEC sub-committee 47E and are not covered in this document. Semiconductor controllers and contactors fall within the scope of the IEC 60947 series of standards – low-voltage switchgear and controlgear – developed by IEC subcommittee 121A and are not covered in this document. IEC 62314:2022 cancels and replaces the first edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) addition of load categories for DC load; b) addition of load category for self-ballasted lamp load; c) addition of "sockets" terminal; d) update of references; e) introduction of the requirement of EMC; f) restructuring of the whole document.
